SunPower Totals 100 Megawatts of Spanish Solar Power Plants

SAN JOSE, Calif., May 29 /PRNewswire-FirstCall/ -- SunPower Corp. (Nasdaq: SPWR), a manufacturer of high-efficiency solar cells, solar panels and solar systems, today announced the completion of two solar-electric power plants in Spain, totaling 8.7 megawatts. The two plants, located in Llerena and Lebrija, were developed by Solarpack, a Spanish company specializing in renewable energy development, investment, consulting and services. Solarpack hosted ceremonies dedicating the two power plants this week.

The solar power plant constructed by SunPower in Llerena is 4.8 megawatts; the plant in Lebrija is 3.9 megawatts. In Spain, SunPower has completed or has signed contracts to deliver solar power plants totaling more than 100 megawatts.

'SunPower's innovative sun tracking technology and solar power plant experience was key to meeting our cost, schedule and energy delivery goals at these sites,' said Jose Galindez, chairman of Solarpack. 'This region of Spain has great potential for the renewable energy sector, and we are proud to be generating clean, emission-free solar power for these communities.'

For these projects, SunPower used its proprietary SunPower(R) Tracker technology, which follows the sun during the day, and delivers significantly more energy than traditional fixed-tilt systems.

'We utilized our industry-leading SunPower Tracker technology at both of the power plant sites, maximizing energy output, while optimizing land use and reducing related costs,' said Marco Antonio Northland, general manager of SunPower's European operations. 'We are pleased that the Spanish market continues its rapid adoption of solar power, and that Solarpack chose SunPower to provide innovative turnkey solar solutions.'
